Michael Sullivan (U.S. Attorney)

Sullivan announced on February 14, that he would collect signatures to run for the Republican nomination in the 2013 special election to succeed John Kerry as U.S. Senator. He relied on volunteers rather than paid organizations to gather signatures. On February 27, he announced that he had gathered the requisite 10,000 signatures to appear on the primary ballot. He faced state Representative Dan Winslow and former U.S. Navy SEAL Gabriel Gomez in the April 30 primary. Sullivan was defeated in the primary by Gabriel E. Gomez who garnered 93,632, or 51% of the votes. Sullivan, gathered 66,164 votes, or 36%, whereas state Representative Dan Winslow, collected 24,057, or 13% of the votes, with 99 percent of precincts reporting shortly before 11:30 pm, on April 30, 2013. Sullivan later endorsed Gomez.

In February 2009, following the inauguration of President Barack Obama, Sullivan announced his intention to resign his position, following the customary practice of U.S. Attorneys, who typically do not retain their posts in a new administrations.

Sullivan resigned as Acting Director effective January 20, 2009 to make way for incoming President Barack Obama to name his own nominee.

Sullivan's residence is in Abington. He and his wife Terry have four children. He has been partner at The Ashcroft Group since 2009. His daughter Alyson Sullivan represents the 7th Plymouth District in the Massachusetts House of Representatives.

Sullivan was a keynote speaker and special guest at the 2007 Great Lakes Summit on Gun Violence conference. This conference was organized by the International Association of Chiefs of Police and funded by a $375,000 grant from the Joyce Foundation. The report of the conference was titled "Taking a Stand: Reducing Gun Violence in Our Communities" and called for the passage of several gun bans and gun control measures. The National Rifle Association has criticized the IACP report, calling it "a rubber stamp, bought and paid for, of the pre-existing agenda for gun ban groups." The report was produced with assistance from the Joyce Foundation's Communications Director and with contributions from gun control advocates such as Kristen Rand and Tom Diaz of the Violence Policy Center. The NRA has called the Joyce Foundation an activist foundation whose "shadowy web of huge donations" leads "straight to puppet strings that control the agenda of gun ban groups".

In 2006, Sullivan was made Acting Director of the ATF by President George W. Bush. The position had been made subject to the Senate confirmation process and Sullivan was the first nominee to be sent to the Senate. Bush nominated Sullivan to be permanent director in 2007, but the nomination was blocked by a Senate hold placed by Senators David Vitter (R-Louisiana), Michael Crapo (R-Idaho) and Larry E. Craig (R-Idaho). They expressed their concern that the ATF is hostile to small gun dealers, pursuing them overzealously for small paperwork infractions and driving law-abiding small retailers out of business. They said that Sullivan was indifferent to their concerns and "exhibits a lack of willingness to address these problems."

He spoke before the U.S. House Judiciary Subcommittee on Crime, Terrorism, and Homeland Security in support of the USA PATRIOT Act in May 2005, urging Congress to make the act's surveillance provisions permanent.

Sullivan presented charges, in Boston, on November 23, 2005, against Abdullah Khadr, an Egyptian from Canada who is alleged to have sold arms to the Taliban.

Sullivan was appointed U.S. Attorney for the District of Massachusetts by President George W. Bush on September 14, 2001, in the wake of the September 11 attacks. His early work revolved around the terrorist attacks, which were launched from Boston's Logan Airport. Sullivan was the prosecutor in the 2001–2002 criminal trial of Richard Reid, widely known as the "Shoe Bomber".

Representing the town of Abington, he was elected as a Republican state representative in 1990. He was voted "Legislator of the Year" by the Massachusetts Municipal Organization in 1994. Among his initiatives was a budget amendment to have the Massachusetts Water Resources Authority charge municipalities for sewage management by volume instead of population, which moved much of the cost burden away from outlying towns and toward Boston. The amendment was adopted by the House but reversed the following day under pressure from Democratic leaders. He stepped down in 1995 after being named District Attorney for Plymouth County. He took early steps to run for the U.S. Senate against incumbent Ted Kennedy in 2000, but retracted before declaring an official candidacy.
